다 주다

fetch it; see someone off

Two everyday verbs are built this way. 갖다 주다 is bringing something over to a person: 편리하잖아요 다 갖다 주고 하니까 'it's handy, they bring everything to you.' 바래다 주다 is going along with someone to where they are headed and leaving them there — 내일 아침 일찍 터미널까지 바래다 줘 'drop me at the terminal early tomorrow', 어머니, 학교까지 바래다 주실 필요 없어요. The 주다 is what makes it a favour done for the other person.
